That is one of the least helpful error messages in VFP, IMHO. :)

IAC,it's usually due to the rowsource for a CBO being incorrectly defined (as Elyse and others are hinting at). Is there a combobox in one of the grid columns, per chance?

>I have a form with a grid with it's recordsourcetype set to Alias and it's record source set to a table which is in the form's data environment. When the form opens the grid appears with the data showing, but immediately I get an error "'field' phrase is not found". When I close the error box the grid disappears, leaving a white box in it's place. I cannot find that error in Help, so what does it mean?
